[Message part 1 (text/plain, inline)]

Hi,

xinit suffers from an upstream bug, which does not allow non-root X to be run without a display manager via startx or xinitrc. Several people have reported this on #guix.

Currently if one runs startx as non-root, X reports:
(EE) parse_vt_settings: Cannot open /dev/tty0 (Permission denied)

This bug is further discussed in [1]. Redhat seems to have a patch [2], but it is unclear to me whether this has been applied upstream.

Did you have a change to try Red Hat’s patch?  It could be a good
starting point.

Thanks for your report,
Ludo’.

Hello, for 'xinit', you can create a '~/.xserverrc` file with:

  tty=$(tty)
  tty=${tty#/dev/tty}
  X vt${tty}

then it will run a non-root X from current tty.  Also 'sx' works fine.

Closing now..
